PROBLEM TO BE SOLVED: To provide a sowing device in which the labor concerning sowing work is alleviated, and the operator of advanced age can efficiently carry out sowing of many seeds to the fixed depth for every one grain by low labor.SOLUTION: The sowing device includes: a guide pipe 1 which has a receiving port 12 for the seed injection at the upper end, and in which the lower end is opened as a seed discharge port 13c communicating with the receiving port 12 a shutter plate 3 which can be rocked to the direction which opens the seed discharge port 13c from a closing position which closes the seed discharge port 13c which is attached at the lower end of the guide pipe 1 and a flat ground plate 5 in which the bottom face thereof contacts with the surface of soil when the lower end of the guide pipe 1 is thrust into the soil. The ground plate 5 is connected with the shutter plate 3, the upper part of the guide pipe 1 is pushed in the direction in which the ground plate 5 is located in the condition in which the lower end of the guide pipe 1 is thrust into the soil, and thereby the seed discharge port 13c is opened.COPYRIGHT: (C)2012,JPO&INPIT【課題】播種作業にかかる労力を軽減し、高齢の作業者でも多数の種子を一粒ずつ一定の深さに低労力で効率良く播種できる播種器具を提供する。【解決手段】上端に種子投入用の受口部12を有して下端が受口部12に連通する種吐出口13cとして開口されたガイドパイプ1と、このガイドパイプ1の下端部に取り付けられて種吐出口13cを閉鎖する閉口位置から種吐出口13cを開放する方向に揺動可能なシャッタープレート3と、ガイドパイプ1の下端部を土壌に突き刺したとき当該土壌の表面に底面が当接する偏平な接地プレート5とを備える。接地プレート5はシャッタープレート3に連結され、ガイドパイプ1の下端部を土壌に突き刺した状態で当該ガイドパイプ1の上部を接地プレート5が位置する方向に押し込むことにより、種吐出口13cが開放する。【選択図】図5
